| 86 | Note: | ||
| 87 | The behavior and the effect of the disable variable depends on the | ||
| 88 | implementation of a particular governor. In the ladder governor, for | ||
| 89 | example, it is not coherent, i.e. if one is disabling a light state, | ||
| 90 | then all deeper states are disabled as well, but the disable variable | ||
| 91 | does not reflect it. Likewise, if one enables a deep state but a lighter | ||
| 92 | state still is disabled, then this has no effect. | ||
